MM74C922 Replacement IC 16 Key Keyboard Encoder This is a drop in replacement for the 74C922. The 74C922-SO is a custom programmed microprocessor designed to emulate the 74C922 surface mount chip that is no longer available. This part is in full production, and large quantities are available. Encode your keyboard or keypad of up to 16 keys with no additional parts required. Functional Description The 74C922-SO contains all the logic necessary to encode a SPST keyboard switch array and provide a 4 bit parallel output and a data available signal. The data available signal goes high when a key is pressed, and goes low before another key output is generated. The data output pins keep their state even after the key is released. The array is often a 4 x 4 array, but smaller arrays such as a 3 x 4 array or smaller can be used. The 74C922-SO handles debouncing the keys as well. No external capacitors are required for timing, all timing is internally generated. No external diodes are required |
